Oh Elbows - now what?

Elbows came home with this singing, moving 'thing' . It's got motion sensors and if it's plugged in, it springs to life as you walk past! It's head and arms move. Clever but creepy. 

Apparently, it belongs to a work colleague who uses it for his Christmas engagements. Oh well, it's quirky.But it keeps making me jump because I think someone is there.
